fix(signals): classify Java gRPC service stubs as generated

[luciferlive112116]

Summary

Extend isGeneratedFile to recognize grpc-java service stubs (*Grpc.java), matching the existing .pb.kt message-stub and *GrpcKt.kt coroutine-stub coverage. Includes direct isGeneratedFile / classifyChangedFile assertions and a hand-authored .java negative case.

Fixes #561

Scope

• The PR title follows type(scope): short summary Conventional Commit format, for example fix(api): restore profile access checks.
• This PR is focused and does not mix unrelated backend, UI, MCP, docs, dependency, and deploy changes.
• This follows CONTRIBUTING.md and does not reintroduce GitHub Pages, VitePress, site/, or CNAME.
• I linked an issue, or this is small enough that the summary explains why an issue is not needed.

Validation

• git diff --check
• npm run typecheck
• npx vitest run test/unit/path-matchers.test.ts (45/45 pass)
• npm run test:coverage — changed lines covered by new positive/negative isGeneratedFile and classifyChangedFile cases
• npm run test:workers — not applicable (signals-only)
• npm run build:mcp — not applicable
• npm run test:mcp-pack — not applicable
• npm run ui:openapi:check — not applicable
• npm run ui:lint — not applicable
• npm run ui:typecheck — not applicable
• npm run ui:build — not applicable
• npm audit --audit-level=moderate — not applicable
• New or changed behavior has unit/integration tests for new branches, fallback paths, and sanitizer boundaries

If any required check was skipped, explain why:

• Signals-only two-file diff; full repo test:coverage runs on CI. Local validation: npm run typecheck + targeted vitest file above.

Safety

• No secrets, wallet details, hotkeys, coldkeys, user PATs, private keys, raw trust scores, private rankings, or private maintainer evidence are exposed.
• Public GitHub text stays sanitized, low-noise, and does not imply compensation guarantees or optimization tactics.
• Auth, cookie, CORS, GitHub App, Cloudflare, or session changes include negative-path tests.
• API/OpenAPI/MCP behavior is updated and tested where needed.
• UI changes use live API data or real empty/error/loading states, not production mock/demo fallbacks.
• Visible UI changes include a UI Evidence section below with JPG/JPEG or PNG screenshots arranged as organized, captioned, clickable thumbnails. SVG screenshots are not used as review evidence. Review-only screenshots or recordings are not committed to the repository.
• Public docs/changelogs are updated where needed; changelogs are only edited for release-prep PRs.

UI Evidence

N/A — signals-only change with no visible UI.

Notes

• Incremental maintenance parity for the path-matcher slop signals from feat(signals): slop signal — generated/vendored/dependency/docs matchers #561. Supports generated-file classification work tracked in feat(miner-foundation): extract deterministic slop signals into gittensory-engine #2279.
• Paths are normalized to lowercase before matching, so the matcher uses the grpc.java suffix (parallel to grpckt.kt).

Review summary
Adds a regex to recognize grpc-java's `*Grpc.java` service stubs as generated output, following the exact same suffix-matching convention already used for Swift's `.grpc.swift` and Kotlin's `GrpcKt.kt` stubs. The change is minimal, correctly placed in the existing regex chain, and is accompanied by both a positive case (`gen/GreeterGrpc.java` → generated) and a negative case (`src/Greeter.java` → not generated) in `isGeneratedFile`/`classifyChangedFile`, plus the classification table entry. The comment above the regex block was updated to document the new plugin output, consistent with the file's existing documentation style.

Nits — 3 non-blocking

• The `/grpc\.java$/` pattern (like the pre-existing `/grpckt\.kt$/`) has no word boundary before "grpc", so a hand-authored file that merely ends in "...Grpc.java" without being protoc-generated would also be misclassified — this is a pre-existing risk class in the file, not new to this PR, so it's worth a shared follow-up rather than blocking this one.
• The negative test only covers `src/Greeter.java`; a case like `src/MyGrpcHelper.java` (containing "Grpc" but not ending in it) or `src/FooGrpc.txt` would further pin down the boundary, though this is optional given the existing pattern's precedent.
• Consider a follow-up issue to tighten the gRPC-suffix regexes (Kotlin, Swift, Java) with a preceding word/class-name boundary check if false positives on hand-authored `*Grpc.<ext>` files become a real problem in practice.

Signal definitions

• Related work = same linked issue, overlapping active PRs, or title/path similarity.
• Change scope = cached public metadata such as size labels, draft state, and review-burden hints.
• Validation posture = whether the PR provides enough public validation/test evidence for maintainer review.
• Contributor workload = public contributor activity and cleanup pressure, not a repo-wide quality failure.
• Contributor context = public GitHub/Gittensor identity context; non-Gittensor status is not a blocker.
